3. Setup and Installation
3.1 Hose Connection
The pump includes multiple hose fittings (1 inch, 1-1/4 inch, 1-1/2 inch) to ensure compatibility with various hose sizes. Select the appropriate fitting based on your required flow rate and hose diameter. Securely attach the chosen fitting to the pump's discharge outlet and then connect your hose.

3.2 Base Configuration
The pump features adjustable bases to adapt to different water conditions:
- Clean Water Base: Filters particles larger than 3 mm. Use this configuration for relatively clean water applications.
- Dirty Water Base: Allows for the passage of solids up to 30 mm. Ideal for pumping water containing larger debris.
- Low Suction: By removing all bases, the pump can drain water down to 1 mm in depth, enabling nearly complete water removal from flat surfaces.

4. Operating Instructions
4.1 Automatic Operation
For automatic operation, ensure the float switch is freely suspended and can move with the water level. The pump will automatically start when the water level rises to approximately 23 inches and stop when it drops to about 8 inches. This mode is ideal for continuous monitoring and drainage in areas prone to flooding.
4.2 Manual Operation
To operate the pump manually, fix the float switch in an upright position using the float switch holder on the pump handle. In manual mode, the pump will run continuously, allowing for drainage down to a minimum stop level of approximately 1/25 inch. This mode is particularly useful when the water level is too low for the float switch to activate automatically or when precise control over drainage is required.

- Storage: When not in use for extended periods, clean the pump thoroughly, drain any remaining water, and store it in a dry, protected area.
6. Troubleshooting
This section provides general troubleshooting advice. For specific issues not covered here, please refer to the manufacturer's support channels. Detailed troubleshooting steps are not available in the provided product data.
- Pump Not Starting: Check power supply, ensure the float switch is not obstructed (in automatic mode), or try manual operation.
- Low Flow Rate: Inspect for blockages in the intake or discharge hose, ensure the correct base is used for the water type, and check for kinks in the hose.
- Pump Running Continuously (Automatic Mode): Verify the float switch is not stuck in the 'on' position or obstructed.
- Unusual Noise: Disconnect power and inspect for foreign objects inside the pump housing.
